Custom value to PI tag

I wanted to confirm whether is there any way by which we can force PI data to display BAD value rather than hold last known value. There are times when data outage/Archive corruption or some other issues can cause misperception of real data (data stops updating), since the PI tags holds last updated value and hence for few applications or Process book screens the PI tag will show a Good value but actually there is issue going on and until and unless one see the timestamp, it won't be known.

There is a parameter under PItoPI-->Opt Cont.--> Suppress I/O Timeout which will suppress writing I/O Timeout to tags upon reestablishment of a lost connection to the source PI server.

Do we have any similar settings which can be done on OPC/PItoPI interface configuration file.

If I understood your problem correctly, you want BAD data as value in PI tag. It is different in case of OPC Interface and PI-to-PI interface.

In OPC Interface, on ICU there is setting under OPCInt as follows:If you uncheck this, you will get bad quality data also in PI tag.

In PI-to-PI Interface, you already know the supress I/O TimeOut setting. Other than that, you also need to check the instrument tag of that source PI tag, data of which is sent via PI-to-PI interface. And according to instrument tag, i.e. from where data in source PI tag is coming, you can check the interface setting of it.Here, if source PI tag will not get bad quality data then you can never get bad quality data on destination PI tag regardless of setting done on PI-to-PI interface.
